Marek Vasut fc91e40123 i2c: mxs: Add PIO and mixed-DMA support ... Add support for the PIO mode and mixed PIO/DMA mode support. The mixed PIO/DMA is the default mode of operation. This shall leverage overhead that the driver creates due to setting up DMA descriptors even for very short transfers. The current boundary between PIO/DMA 8 bytes, transfers shorter than 8 bytes are transfered by PIO, longer transfers use DMA. The performance of write transfers remains unchanged, while there is a minor improvement of read performance. Reading 16KB EEPROM with DMA-only operations gives a read speed of 39.5KB/s, while with then new mixed-mode the speed is blazing 40.6KB/s.
